Another semester has begun! We are excited to welcome one of two new Ph.D. students who be working in our group supported by the NSF CAREER Award. Carlos López has recently arrived from Colombia, and will be working on the processes associated with severe thunderstorms around the world. In other news, we have 3 summer research internship opportunities for summer 2021, working on dryline climatology, hail environments and global severe convection.

Another busy semester has drawn to a close, and topping off a great year, congratulations to Cameron Nixon on his first paper from his Ph.D. research 'Anticipating Deviant Tornado Motion Using a Simple Hodograph Technique', in Weather and Forecasting. This joins 11 other publications in what has been a great year for our group, including 2 papers lead-author by Alumnus Dr. Maria Molina, who has become a project scientist at NCAR. We look forward to new graduate and undergraduate students joining the group over the next months to begin new adventures in a bright new year!

Despite the challenges of COVID-19 research continues. Dr. Allen will be collaborating with Dr. Amy McGovern from AI2ES at the University of Oklahoma on a new project to look at transitioning automated front detection to first guess guidance for operational frontal analyses under a new NOAA JTTI project. This project will provide undergraduate opportunities for the next two summers and support Alyssa Woodward, a Masters student at the University of Oklahoma co-advised by Dr. Allen.

Exciting News! Dr. Allen has been awarded an NSF Faculty Early Career Development (CAREER) award! This is a prestigious 5-year award that will provide support to further our understanding of severe convection and its impacts around the globe and its links to a changing climate. You can read more details about the project here. It will also support a number of student opportunities for undergraduate and graduate students, and in collaboration with NCAR's SciEd program, develop educational resources and modules.

The new year has begun with a bang for our research group, with 12 contributions of oral and poster presentations at the 100th AMS Annual Meeting. Everyone did a great job, with excellent presentations in the main conference from Olivia VanBuskirk, Nicholas Bogen, and Daniel Butler. There have also been four new publications, including another paper from the highly productive Dr. Maria Molina, a review of hail science from Dr. Allen, and collaborations looking at hail size in China and sub-seasonal forecasting over severe weather in the US. Dr. Allen also was announced a recipient of the Provost's Award for Outstanding Research and Productivity.

August 27th 2019
As the year marches on, our group has continued to have success. Dr. Allen was a recent receipient of the '2019 Central Michigan University College of Science and Engineering Award for Outstanding Research'. This award would not have been possible but for the work of the group and collaborators. We also welcome two new group members for the semester; Elizabeth Wawrzyniak and Dennis Weaver.

August 1st 2019
As of August 1st our group has new support in the form of an NSF PREEVENTS grant (NSF-AGS1855054) 'PREEVENTS Track 2: Collaborative Research: Improving High-Impact Hail Event Forecasts by Linking Hail Environments and Modeled Hailstorm Processes', in collaboration with Dr. Rebecca Adams-Selin (AER), Dr. Matthew Kumjian (Penn State), and Dr. Conrad Ziegler (NSSL). As part of this new project, we have a new group member, Cameron Nixon, a Ph.D. student who will be joining us from Texas Tech. He will be working on hail forecasting research related to the project, with a specific focus on wind fields.

Maria Graduation
Big news for our group! I am pleased to announce that Dr. Maria Molina successfully defended her Ph.D. Dissertation on April 22nd 2019. Congratulations Maria! Maria will be leaving our group at the end of the summer (2019) to begin an NCAR ASP Postdoctoral Fellowship in Boulder. Picture above is from Maria's commencement cermony on May 3rd.

New Paper Alert! Maria's second Ph.D. related paper has recently appeared as an early online release in Journal of Climate 'On the Moisture Origins of Tornadic Thunderstorms' - you can check it out here.

March 19th 2019
Student News! It is a busy summer ahead for the group with Olivia Vanbuskirk heading off to University of Michigan for the summer as part of the REU program down there. Congrats to Olivia. Meanwhile, Dan Butler will be out in the field with the TORUS field campaign with Dr. Jason Keeler and will be continuing his tornado research with the group.

March 8th 2019
New Paper Alert! In a new collaboration with colleagues from Europe led by Mateusz Taszarek, we published a European Climatology of Thunderstorms and Severe Thunderstorms using a mixture of data sources, including thunderstorm reports, lightning data and environmental proxies. This paper has proven very popular since its release in March, and is the most read Journal of Climate paper in the past 12 months and 5th most read AMS journal publication in the past year! The paper is entitled 'A Climatology of Thunderstorms across Europe from a Synthesis of Multiple Data Sources' - and you can check it out here.
